Effect of Odd Number of Rotor Slits on the Performance of a High- Speed, High-Power, Solid-Rotor Induction Motor

Abstract:- The effect of the number of the rotor slits on the performance of a high-speed, high-power, solid-rotor induction motor is numerically studied using two-dimensional finite element analysis. The theoretical background on the selection of the rotor slit number is presented. The effect of the odd number of the rotor slits on the motor torque ripple as well as on the unbalanced magnetic pull between the stator and the rotor is discussed in detail. Key-Words:- Solid rotor, induction motor, numerical analysis, unbalanced magnetic pull
